Not sure that I've seen it around but I've got the vinyl LP issued on Affinity, a division of Charly Records in the UK. My copy was issued in 1986. It was issued under the name of Billy Strayhorn's Septet ( Strayhorn, Qunetin Jackson, 'Cue Porter', Shorty Baker, Russell Procope, Al Hall, Oliver Jackson ). Recorded 14 April, 1959. A fine record if I remember correctly, although I haven't played it in a while. Not sure whether it has ever been issued on CD.
It was issued on CD.
